As the metric system spread around the planet, its adoption was uneven, resulting in common present-day occurences such as the 7mm socket for a 3/8"-drive ratchet, and a 235mm wide tire for a 15" wheel.

The American War on Metric starts here! We must never give an inch. Mark my words, if the metric system is allowed to get a foot hold here, it will be mere hours before it is in our own back yard. We must muster every ounce of courage we have and relentlessly pound our enemy furlong as it takes until we drink from that sweet cup of victory with the rod of the triumphant in hand!
